“…La literatura muestra que las plantas exóticas afectan a diversos ecosistemas y a los Parque Naturales de América, principalmente de Argentina y Chile. Por ejemplo, Parque Nacional los Alerces, Argentina (58.50 % de las plantas medicinales; Toledo y Kutschker, 2012); Parque Nacional La Campana, Chile (14 %; Hauck et al, 2016); Cordillera de la Costa, Valparaíso, Chile (34 %; Teillier et al, 2010); bosques de Maule, Chile (6.50-28.30 %; Becerra y Simonetti, 2013); bosque templado andino (15 %; Rojas et al, 2011), en la región Mediterránea de Chile central (66.60 %; Figueroa y Cavieres, 2012).…”

“…Esto no indica que las condiciones ambientales sean adversas para el crecimiento de especies nativas con un propósito ornamental o urbanístico. Hauck et al (2016) señalan que el 92.70 % de las plantas exóticas que habitan en los márgenes de los senderos del Parque Nacional La Campana, Chile son de origen euroasiático-noroafricano. En "Passo da Ilha", comunidad rural de Pato Branco, Brasil, predomina el uso medicinal de plantas originarias de Europa (Marchese et al, 2009).…”

An in situ inventory is made of the native and introduced plant species that are cultivated and marketed in the four Pelileo plant nurseries, and all of their owners are interviewed. The dual hypothesis that the nurseries represent an economic and business option for the integration of women in rural areas and that the use of introduced plant species in the nurseries is superior to that of native species in Pelileo, Tungurahua, Ecuador is validated. The main objective is their characterization. These nurseries are individually organized with less than 20 years since their creation, limited infrastructure, few employees, and low production volume. Half are the entrepreneurship initiatives of middle-aged women and 75 % of their owners do not have professional and technical degrees. They have cultivated and commercialized 129 species that have not been labeled nor is their origin reflected; they correspond to 50 botanical families, the majority of which belong to Crassulaceae, Rosaceae, Lamiaceae, and Solanaceae. Among the species 84.50 % are introduced from America, Asia, Africa, Europe, and Oceania. The species are mainly perennial herbs, shrubs, and trees. The nurseries are a type of producer-marketer mix with 70.54% of the species being used for ornamental, food, medicinal and forestry purposes, which are sold cheaply directly to the public. Half of the nursery workers are completely dedicated to their nurseries. They have diverse training needs and their suppliers are national. These nurseries promote sustainable self-employment and constitute a strategic response to the limitations of a rural environment, especially in regards to the incorporation of women into the sustainability of a paid living.

“…Biochar in Peru is used mainly for soil and crop improvement, displaying considerable effectiveness in accelerating the germination of certain plants, such as Quararibea cordata, and increasing yield and profitability in the production of cereals such as corn, thereby contributing to the development of sustainable agriculture in Peru (Andina, 2016;Herrera et al, 2018;Ladd et al, 2017;MINAM, 2015). The popularity of this material is increasing over time, leading to the implementation of biochar processing plants and the addition of the pyrolysis process in some solid waste treatment plants, in order to obtain biochar as a by-product (El Comercio newspaper, 2019).…”

“…In the search for a direct application of this organic waste, which is economical and friendly to the environment, efforts have been made to develop its use in the production of biofertilizers [ 2 ] or biofuels [ 3 ]. However, none of these options meets the above requirements since in most cases, the waste must be collected and transported to processing centers, which increases costs; otherwise, the alternative option is to leave the waste in municipal landfills, where the separation of biomass can be conducted for different purposes, but not for the production of energy since there are no facilities for this purpose at the municipal level, so they only accumulate, causing sources of infection and damage to the environment [ 4 , 5 ].…”

The present work reports the synthesis and the physicochemical characterization of biochar from the organic wastes of nopal (Opuntia Leucotricha), coffee grounds (Coffea arabica) and Ataulfo mango seeds (Mangifera indica) as alternative electrocatalyst supports to Vulcan XC-72 carbon black. The biochars were prepared using pyrolysis from organic wastes collected at three temperatures, 600, 750 and 900 °C, under two atmospheres, N2 and H2. The synthesized biochars were characterized using Raman spectroscopy and scanning electron microscopy (SEM) to obtain insights into their chemical structure and morphological nature, respectively, as a function of temperature and pyrolysis atmosphere. A N2 adsorption/desorption technique, two-point conductivity measurements and cyclic voltammetry (CV) were conducted to evaluate the specific surface area (SSA), electrical conductivity and double-layer capacitance, respectively, of all the biochars to estimate their physical properties as a possible alternative carbon support. The results indicated that the mango biochar demonstrated the highest properties among all the biochars, such as an electrical conductivity of 8.3 S/cm−1 at 900 °C in N2, a specific surface area of 829 m2/g at 600 °C in H2 and a capacitance of ~300 mF/g at 900 °C in N2. The nopal and coffee biochars exhibited excellent specific surface areas, up to 767 m2/g at 600 °C in N2 and 699 m2/g at 750 °C in H2, respectively; nonetheless, their electrical conductivity and capacitance were limited. Therefore, the mango biochar at 900 °C in N2 was considered a suitable alternative carbon material for electrocatalyst support. Additionally, it was possible to determine that the electrical conductivity and capacitance increased as a function of the pyrolysis temperature, while the specific surface area decreased for some biochars as the pyrolysis temperature increased. Overall, it is possible to conclude that heat treatment at a high temperature of 900 °C enhanced the biochar properties toward electrocatalyst support applications.
